Subject: Some small changes (#1869)

All dissector callbacks should not be exported by the library; make static
some other local functions.
The callback logic in `ndpiReader` has never been used.
With internal libgcrypt, `gcry_control()` should always return no
errors.
We can check `categories` length at compilation time.
